SLIP-RING SOCKET.

Application filed October 19,1927. Serial No. 227,194.

. My invention relates to fishing apparatus for use in the drilling of wells, and more particularly to a device which may be termed as slip ring socket adapted to be lowered into a well casing to engage and remove a broken drill part therefrom.v I p At present it is the practice to employ a collar socket to remove broken drill members from the bottom of the well. 'This delo vice, however, cannot be satisfactorily utilized to remove a drilling bit out of a tight hole in a deep well.

An object of my invention is the provision of an improved fishing tool for removing l5 broken tool parts from a well.

Another object of my invention is to provide a socket which is not only adapted to fish broken bits from a shallow well but may be used equally well to remove a broken bit from a tight hole in a deep well.

In accordance with the general features of my invention I provide a socket comprising telescoping sleeves, and sli s carried by one of said sleeves adapted to uncovered by the movement of the other sleeve, whereby said slips will engage the broken drill part, said latter sleeve being movable by the. broken drill member enga 'ng the same.

In accordance with other features of the invention I provide means for preventing the movement of the movable sleeve by foreign matter such as mud or slime, whereby it will only be actuated when it is engaged by the broken drill member, thus enabling the slips to at all times enga e either the movable sleeve or broken dril member. This means preferably takes the form of a'wooden pin adapted to be sheared by the upward movement of the movable sleeve when the same is actuated by the engagement of it by the broken drill member.

Other objects and advantages of my in vention will more fully appear from the following detailed description taken in con-\ sleeve 17. This sleeve includes a nection with the accompanying drawings, which illustrate several embodiments thereof and in which:

In the drawings:

Like reference characters designate similar parts throughout the severalviews.

The reference character 10 designates generally the body of my novel socket shown in Figure -1. The upper end of this body is provided witha threaded ortion 11 adapted to be coupled to a string oi pipe for lowering the socket into a well casing such as the easing 12 shown in Figure 3. The lower portion 13 of the tubular member is enlarged and provided with a bore 14. The extreme lower end v of this portion 13 is cut on a slant, as indicated at 15, in order to provide the body portion with an eccentric point or portion 16 adapted to facilitate the alignment of the broken drill member with the bore 14, as will be more fully explained hereinafter.

Positioned within the bore 14 is a moyablefa air 0 diametrically opposed elongated s ots 18 through which 'extends a transverse pin 19 having its ends mounted at 20 in theannular wall comprising-the body portion 13. Positioned above the pin 19 and disposed parallel thereto is a wooden pin 21 which also hasits ends mounted in the wall of body portion 13. This pin is adapted to be. sheared by the telescoping sleeve 17, as will become more apparent with the progress of the present description. Communicating with the upper end of the bore 14 is a slanting hole or aperture 22 formed in the body 10. This aperture 22 Comprises an outlet for any water which might be forced up into the bore 14.

The lower end of body portion 13 is provided with a plurality of parallel annular grooves 23, in each of which is disposed an annular slip or wedge'24. Each of the annular seats 23 is defined by a slanting surface 25 and a shoulder 26. The slip 24 has a wedge-like cross-section and is adapted to be seated in the groove or seat 23 with its outer slanting surface 27 (Figure 7) opposite the slanting surface 25 defining the seat. In Figure 7 it willbe noted that the slip 24 has a vertical inner surface provided with a pluwords, I have provided a split annular slip adapted to be mounted in the seat 23.

The operation of this form of my invention is briefly as follows:

The socket is lowered into the well casing 12 (Figure 3) until the lower end of the movable or telesco ing sleeve 17 strikes the upper end of the broken drill member or pin 30. It will be readily evident that the eccentric point 16 on the lower end of the body portion 13 facilitates the alignment of the pin 30 with the bore 14. The wooden pin 21 serves, during the lowering of the socket, to prevent the sleeve 17 from being displaced upwardly by any slime or mud which might be forced into the bore 14 of the body portion 11. However, upon the engagement of this sleeve by the drill pin 30, the sleeve will be forced upwardly resulting in the shearing of the pin 21, as shown in Figure 4,.whereby the sleeve is free to continue on its upward travel. This broken pin 21 gravitates through the tube 17 until it strikes the upper end of the broken drill pin 30, as shown in Figure 5. It is to be understood that this pin 21 must be replaced after each use of the socket. Obviously as the sleeve 17 travels upwardly, it uncovers the slips 24 which are immediately covered by the outersurface of the drill pin 30. This arrangement prevents the sli s from being displaced from their seats. e pin 19 normally serves as a means for preventing the sleeve 17 from accidentally falling out of the bore of'body portion 11, as is evident from Figure 3. Of course, the slips 24, due to them frictionally engaging the sleeve 17 will to a certain extent prevent the sleeve from gravitating from the body portion 11.

As shown in Figure 5, the sleeve 17 continues its upward movement in the bore 14 until it strikes the portion of the body deescape from the body portion through the aperture 22, as previously described.

Now obviously upon the upward movement of the device, as shown in Figure 5, the wedges or slips 24 will be forced downwardly into tight engagement with the pin 30, whereby the drill pin or member 30 is firmly wedged to the body portion 11 so that it may be withdrawn with the socket from the well casing 12.

In Figure 8 I have illustrated a modification of my invention, wherein the slips 24 are adapted to engage the inner surface of tubular tool member 30". This form of my invention includes a body 31 adapted to be suitably coupled to a string of 'pipe (not shown). The lowerportion of this body 31 is provided with a plurality of seats 23' adapted to receive annular slips 24 of the same construction as the slips 24. Extending through the body 31 is a passageway 32 which discharges into a slanting passageway 33 in the upper end of the body 31. This passageway 32 is adapted to permit the slime or mud to escape from under the socket member- 31 and through the slanting opening 33.

Disposed concentric with the body 31 and slidably mounted thereon is a sleeve. 34 which is adapted to normally retain the slips 24' to be removed fromthe well casing, it is held from further downward movement with the body 31, and as a result the lower end of the body member enters the opening of the tool member 30. As the slips 24' pass outfrom under the sleeve 34, they immediately come into cont-act with the inner surface of the member 30. When as many of the slips 24 have entered the tool member 30 as. is possible or as is required, the. body member 31 comprising the socket may be moved upwardly. Obviously the upward movement of the body 31 Wlll result in the slips 24 being wedged between the tool member 30 and the lower portion of the body, 31, whereby the tool member 30' can be drawn upwardly with the socket. i

Now, of course, it is to be understood that although I have illustrated and described in detail the preferred forms of my invention,
